STEPHEN D. NEEDHAM, OF RANTOUL, KANSAS.

TRANSPORT-TRUCK FOR DISK HARROWS.

To all whom it may concern:

Be it known that I, STEPHEN D. NEED- HAM, a citizen of the United Statesof America, residing at Rantoul, in the county of Franklin and State ofKansas, have in vented certain new and useful Improvements inTransport-Trucks for Disk Harrows; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention, suchas will enable others to make and use the same, reference being had tothe accompanying drawings, forming a part of this specification.

The objects of the invention are: First, to provide a traveling relayfor the elevation and transportation of movables in transit. Second, toprovide a traveling support for such implements as disk harrows to andfrom the field, and third, to provide an auxiliary traveling support forany disabled conveyance.

The invention consists in the novel construction and combination ofparts such as will be first fully described, and then specificallypointed out in the claims.

In the drawings: Figure '1 is a view in perspective of a disk harrowshowing the novel transport in rear of the harrow, and in position forforward movement. Fig. 2 is a side view of the harrow and transport asseen in Fig. 1, showing their position before the elevation of theharrow in dotted lines. Fig. 3 is a plan view of the harrow and thetransport as seen in Fig. 1.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

For the purpose of elevating the separate frames of the disk harrow asshown, I employ a longitudinal beam 32 of a suitable length. Portions 33of the ends of beam 32 are bent at right angles, and extend downwardly aconsiderable distance forming fulcrum posts, and portions 34 of thelower ends of the fulcrum posts are bent at right angles and extendedoutwardly a short distance in opposite directions to form axle bearings,and upon said bearings are mounted the spoked wheels 35, which wheelsare secured on the bearings by the split keys 36. Upon the longitudinalportion of beam 32, and extending the length thereof is a looselyarranged sleeve 37.

38 indicates the stretcher bars or arms of the stretcher of thetransport which consist of angle bars, the inner ends of whichSpecification of Letters Patent. Application filed June 9, 1911.

bars are mounted upon the upper surface of sleeve 37the verticalportions of the angle bars being cut away adjacent said sleevethehorizontal portion 39- bearin upon said sleeve. The portions 39 of theangle bars are secured adjustably to the sleeve by means of the U-shapedclamping bolts 40, the ends of which bolts are screw threaded at 41, andsaid ends extended past the sleeve 37, and through the plates 39, andupon said threaded ends of the bolts are secured the clamping nuts 42.From the horizontal port-ions 39 of the angle bars of the stretcher thesaid bars are bent at an angle and extended forwardly and downwardly ashort distance to a point 43, and at said point the arms or bars arebent at a slight angle and extended forwardly, and inclined downwardlyin a slight degree to a point or crotch 44. From said point or crotch44, the remaining portions of the arms extend forwardly in an upwardlyinclined plane terminating in an upwardly extended U shaped graspingportion 45, the vertical port-ion of the angle bars in the U shaped beamgrasping portions of the bars being cut away at 45*, as seen in Fig. 1.

Extending around the lower portions of the fulcrum posts 33, are clasps46, the free ends being secured by the clamping screws 46*. To theclamping screws 46*, between said free ends of the clasps are pivotallysecured the inner ends of the brace rods 47, the forward ends of whichrods extend forwardly approximately to a point in line transversely withthe crotch 44 in the stretcher arms or bars 38 when said bars areoperatively connected with the disk harrow. Upon said forward ends ofrods 47 are hooks 48, the portions of the hooks extending upwardly fromthe rods being bent backwardly a slight distance as seen in Figs. 1 and2, so as to resist a direct upward movement when engaged with the diskharrow without first imparting a forward pull on the fulcrum posts 33 ofthe transport to disengage them.

Upon the outer surface of the stretcher bar 38, on the right hand sideof the transport a slight distance forward of the crotch 44 is securedan eye plate 47*.

50 indicates the elevating lever on the transport which is approximatelyof the same length as the longitudinal portion of the main beam 32aportion --51 of ously the requisite which lever is bent at right anglesand inserted within a socket 52, secured to the rear surface of thefulcrum post 33, on the right hand side of the transport-said socket issecured to the fulcrum post by means of the U shaped bolt 53, havingscrew threaded end portions, which extend through the ends of theclamping plate 54, and upon said ends are the securing nuts 55. Upon theupper end portion of the fulcrum post 33 on the left hand side of thetransport, is secured a spring catch plate 56, one end of which catchplate extends rearwardly a short distance, and is bent forwardly aslight distance upon the free end of the elevating lever 50, so as toretain said lever in a folded posit-ion parallel with the sleeve 37, onthe longitudinal portion of beam 32. The forward portion of the catchplate 56 supports a clip 56*.

In operation the main beam 32 of the transport is moved forwardly anddownwardly in position until the bent portions between the point 43, andthe crotch, 44, rest upon the ground. The forward ends of the stretcherarms are then extended for-- wardly beneath the respective shafts 12 and14 of the disk harrow until the crotches 44, in said arms, are directlybeneath said shafts, in which position the U-shaped portions 45, of saidarms are hooked over the upper surface of the main draw beam 24, of thedisk harrow. The free end of the elevating lever 50, is released fromthe catch 56, and moved outwardly and rearwardly. Power being applied tosaid end of the lever, a leverage is obtained on the fulcrum post tomove the wheels 35, of the transport-forwardly in the direction of thedisk harrow, thereby elevating both shafts 12 and 14, carrying the disks15 simultanedistance above the ground. The hooks 48, on the ends of thebrace rods 47, are then hooked over the sleeves 16, on shafts 12, and14, separating the disks from each other. The harrow may now be moved toand from the field, supported by the wheels of the transport.

In detaching the transport from the harrow, the hooks 48, are disengagedfrom the sleeve 16, and under controlling lever 50, the sections of theharrow are lowered until the disks 15, rest upon the ground. Thegrasping ends 45, of the stretcher arms are then released from the beam24. The beam 32 is then elevated by lever 50, and the hook 48 on the rod47 on the right hand side of the transport is engaged with the eye 47 onthe adjacent stretcher bar, and the rod 47 on the left hand side of thetransport is elevated in posit-ion, as seen in dotted line in Fig. 1,and is held in said posit-ion by the clip 56*.

The invention is applicable as relay for the transport of disabledvehicles whenever a tire or'axle may be grasped by the stretcher arms,or in many instances the transport may be utilized for the conveyance ofmovable commodities or bodies.

In the employment of the transport for disk harrows, its efiectivenessin the application of power to raise the disks will be at once apparent.

Such modifications of the invention may be employed as are within thescope of the appended claims.

Having fully described my invention, what I now claim as new and desireto secure by Letters Patent is.
